Abstract

A flux-corrected switching power converter includes a first transformer, a first switching stage, a controller, and a flux correction current source. The first transformer includes a first magnetic core, a first primary winding, and a first secondary winding, and the first switching stage is electrically coupled to the first secondary winding. The controller is configured to control switching of at least the first switching stage. The flux correction current source is electrically coupled to the first primary winding, and the flux correction current source is configured to inject current into the first primary winding to at least partially cancel magnetic flux in the first magnetic core that is generated by current flowing through the first secondary winding.
